Using the Greenlee 659 Tray - Type Cable Pulling Sheave is easy. First, attach the steel frame to your cable tray, which can be up to 2 inches thick. Then, place the cable in the sheave and start pulling. The self - lubricating bearings in the 5 - inch wide aluminum alloy sheaves will ensure smooth operation. When using, make sure the cable is properly seated in the sheave to avoid any jams. For maintenance, check the self - lubricating bearings regularly. If they seem to be getting dirty, gently clean them. Store the sheave in a dry place when not in use to prevent rust on the steel frame.
